The roads here in Seattle are mostly asphalt and as I've mentioned before, they're often terrible. I talked to someone about it once and he said that every few years they'll repave the road with new asphalt but it only takes a few months for snow tires and ice to create cracks and bring back the same potholes that were there before.

Recently, though, the city has been repaving some of the major roads around here with concrete. As they were digging up the layers of asphalt, I noticed that these layers had just been laid on top of bricks, so the roads are pretty old. They had to remove these bricks to lay concrete and had a few lanes closed while doing one side of the street. The side they did in concrete was very smooth, so I was excited to see what things would look like when they finished both sides.

However, for some reason, it appears that they continued repaving these roads with asphalt. But, wait, why? Why didn't they just continue repaving with concrete? I don't know. Maybe they'll go back later and dig up the asphalt and finish repaving with concrete? Who knows. We don't drive that much, so it's actually not a big deal as long as they keep the sidewalks open, but I wonder why they'd ever use asphalt again.
